The April-June, 2013 Status Report is now available with 33 entries.
We’ve never had a group of student post progress this regularly. It’s great! Daniel Flores: HAMMER2 compression feature Larisa Grigore: System V IPC in userspace Pawel Dziepak: Make vkernels checkpointable Joris GIOVANNANGELI: Capsicum Mihai Carabas: hardware nested page table support for vkernels
Open Help is an annual conference for people who write documentation for an open source project. The Foundation sponsored Warren Block from the FreeBSD documentation team to attend this year. He writes:In June, I attended the Open Help Conference in Cincinnati, Ohio. Open Help focuses on open source documentation. Dru Lavigne atte [...]
Busy, busy week. An in-depth programming language comparison. These can be fun for reinforcing your language choices, but also interesting just for the depth of comparison. Spoiler: Java can be crazy slow; Perl can be crazy fast. The page has lots of charts which always make me happy. The quotes at the end per-language are enjoyable. (vi [...]
Something new and odd: A port of the Hammer (1) filesystem into Go, for go-fuse. As the author has said, it’s more for the practice of learning Go and Hammer than for producing anything useful. Still, an interesting way to learn.
As usual, a lot of interesting things are going in The Internet, here are some that caught my attention: 1) Mozilla Persona A better way to sign in. It can be used to implement SSO (Single-Sign-On), in someway it is similar to OpenID. The identity provider is not notified, which is very good for privacy. … Continue reading →
BSDTalk 228 has a nearly half-hour chat with Michael W. Lucas at BSDCan 2013.
I was trying to recompile sysutils/bacula-client on a FreeBSD 8.4 jail when I encountered some perplexing link errors. It took me a while to figure it out, but with the help of some IRC conversation, we figured it out. I started off by deleting the old (quite old) port: bacula-client-5.0.3 Then I recompiled: cd /usr/ports/sysutils/bacula-clie [...]
Michael W. Lucas auctioned off his first copy of Absolute OpenBSD, 2nd Edition some time ago, with the proceeds going to the OpenBSD Foundation. It was to be signed by OpenBSD developers – which is neat enough, but apparently it was annotated by the developers, too.
Apparently Sepherosa Ziehau has been improving DragonFly’s route table performance under extremely heavy load. (e.g. run efficiently; don’t die) I don’t have a definitive commit message to point at, but looking at his recent commits are a good start.
I recently upgraded a jail server from FreeBSD 8.2 to FreeBSD 8.4. This stopped various jails from starting their own instances of PostgreSQL. The messages in the logs were: Jul 9 14:48:48 building postgres: [2-1] FATAL: could not create shared memory segment: Function not implemented Jul 9 14:48:48 building postgres: [2-2] DETA [...]
Encryption seems to be the accidental theme tonight. A question about Hammer 2 and encryption prompted this list of possible solutions from Matthew Dillon. Hammer 2 is still months out, so these features both require time and someone interesting in doing them – though they sound quite possible. Still not sure if I should be writing Ha [...]
If you were wanting to encrypt your /home directory, Pierre Abbat has written up the explicit steps he took to do that very thing.
I recently upgraded a jail server from FreeBSD 8.2 to 8.4, and part of that process involved recompiling all of the applications. Along the way, nrpe on one jail stopped working. Nagios was reporting: CHECK_NRPE: Socket timeout after 10 seconds. Trying from the command line gave: $ /usr/local/libexec/nagios/check_nrpe2 -H -H dbclone.example.o [...]
Week 3 is underway, and the students are starting to get into the meat of their projects: Daniel Flores: HAMMER2 compression feature Larisa Grigore: System V IPC in userspace Pawel Dziepak: Make vkernels checkpointable Joris GIOVANNANGELI: Capsicum Mihai Carabas: hardware nested page table support for vkernels
The pkgsrc-2013Q2 branch has been out for some days, but the official release announcement has now been published, with details on the number of ports. You should be able to pull it down from dragonflybsd.org via git, by the way.
A U.S. holiday and very warm weather has made this a less intense week. At least for links. Someone help. A problem I never anticipated. (via) Git Cheat Sheet. This one’s for printing. (via) Real Life Tron on an Apple ][gs. (via) Neocities, an excellent idea. Follow the suggested links. (Read more...)
For the past 2 weeks, meat space have been a busy but very interesting one. Much to my realized the world without BSD are wild & unstable, but yet surprisingly interesting. I wouldn't recommend anyone with less sanity to spare but if you must have a dangerous adventure, try linux kvm on a (mere) load average of 38 with dual (Read mo [...]
Kris has announced that the PC-BSD project has moved over to a CDN (content delivery network) service for its network backbone. The CDN will replace the existing system of mirrors the project used for many years. It also means that users will no longer have to pick a mirror close to their geographical location in order to get decent download [...]
